Does anyone else get palpitations? I had palpitations once before when I first went on Levothyroxine and the doctor was getting my dosage right. I've been ok for years on my dosage of 125. I've started with palpitations again couple of months after being put on 'new formulation' I don't know if it coincidence or have they changed an ingredient and my body getting use to changes etc. Advance thank you to any replies.
